Write Joule’s law of heating
Write Joule’s law of heating.
Answer
Joule’s law of heating
Heat produced in a resistor is
- directly proportional to the square of current for a given resistance,
- directly proportional to the resistance for a given current and
- directly proportional to the time for which the current flows through the resistor
H = I2Rt
where,
- H = Heat produced
- I = current
- R = Resistance of the conductor
- t = Time for which the current flows through the resistor
